Ingredients

Scale
  • 1 box (15.25 oz) chocolate cake mix
  • 1 package (3.9 oz) instant chocolate pudding mix
  • 2 cups milk
  • 1 cup mini peanut butter cups (plus extra for topping)
  • 1/2 cup peanut butter, melted
  • 1/2 cup unsalted butter, melted
  • 1/2 cup chocolate chips (optional)

Instructions

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

In a medium bowl, whisk together the pudding mix and milk until slightly thickened, about 1 to 2 minutes.

Pour the pudding mixture into the bottom of the prepared baking dish and spread it evenly.

Sprinkle the dry chocolate cake mix evenly over the pudding layer. Do not stir.

Drizzle the melted butter and melted peanut butter evenly over the cake mix layer.

Sprinkle the mini peanut butter cups and chocolate chips on top.

Bake for 35 to 40 minutes, or until the top is set and bubbling around the edges.

Let cool slightly before serving. Optionally, top with extra peanut butter cups just before serving.

Notes

  • Don’t stir the layers—it’s the key to the classic dump cake texture.

  • Use mini peanut butter cups for better melt distribution.

  • Want it extra gooey? Don’t skip the pudding layer.

  • Cool for at least 10 minutes before serving to help it set.

  • Serve warm with ice cream or whipped cream for best results.
